PD also says fabric testing should be done annually, but most senior riggers that are probably in your local area do not have the equipment available to do that. A lot of bigger lofts do have this equipment though. If in doubt, send it to PD for an inspection, only $25 + return shipping usually $20-30, and they will make sure it is good to go.

FABRIC TESTING STRENGTH Fabric testing should be done annually (at the appropriate repack cycle), however it is not necessary to test the fabric before the first pack job if the parachute is within one year of the date of manufacture. When the fabric is tested, note this on the packing data card. Use commercially available 1 inch (2.54 cm) wide fabric testing clamps with rubber faced jaws and appropriate scale. The scale should be calibrated at least once per year and be accurate within 1.0 lbs (0.4535 kg).
